Got it Jim, thanks! Your help got me looking in different places than I would have for the solution and came up with this: SELECT MasterTypeID.TypeID, MasterTypeID.TypeDesc, MasterTypeID.Number, (DMax([Number],"MasterTypeID")+1) AS NextNumber FROM MasterTypeID WHERE (((MasterTypeID.TypeID)=[forms]![selectordertype]![typeid])); "Jim Pettit" <jimpettit@xxxxxxxx To: <mso@xxxxxxxxxxxxx> m> Sent by: cc: mso-bounce@freelist s.org Subject: [mso] Re: Access 2002: DMax Problem 08/30/2005 10:58 AM Please respond to ..... mso Cathy-- With the form objects in quotation marks like that, Access can't "see" the value you want it to see; it's trying to find a record that matches the name of the box. ;-) Try this instead: SELECT TypeID, Type, Number, DMax("Number", "MasterTypeID", Forms!Selectordertype!Cbotype) + 1 AS NextNumber FROM MasterTypeID That'll work if the bound column for your combo box is the one you want, if not, you'll have to go with this: SELECT TypeID, Type, Number, DMax("Number", "MasterTypeID", Forms!Selectordertype!Cbotype.Columns(?)) + 1 AS NextNumber FROM MasterTypeID --Jim ----------------------------------------------------------------------------------------------------- The information transmitted is intended only for the person or entity to which it is addressed and may contain proprietary, business-confidential and/or privileged material.
